How can I get URL encoded links to work in Outlook 2007? Anybody?

Question

From one of our applications we send an email out with a URL (link) in it. We URL encode that link for multiple reasons. One of the things we encode is the period which we represent as %2E. In Outlook 2003 this works fine. If you hover over the link, the %2E gets translated to a period and if you click the link it will open the browser with the correct link in it. The problem in Outlook 2007 is that the %2E does not get translated to a period by the Outlook client. The email is in HTML format. This does work in Outlook 2003
